Loading thread data ...

AFIUI (and I've never actually handled one), auto-iris CCTV lenses use a galvanometric arrangement where the iris steady-state position is determined by the force of a coil operating against a spring (Hooke's law and ampere-turns).

There's typically another coil that provides a velocity signal for damping the control system.

The drive coil is something like 180 ohms so a bit more than 20mA and

4V drives it all the way (open, I would assume, since old-school vidicons could be easily damaged by high light levels).

Check with Jan Panteltje over in s.e.d. He had a package that was lost in the Ohio area for a while. Maybe it's his?
